Environmental problems have become increasingly complex. The procedures for investigating these problems cross the traditional boundaries of organic and analytical chemistry, microbiology and biology. Organic Chemicals: An Environmental Perspective brings together the basic issues of chemical analysis, distribution, persistence, and ecotoxicology.The author illustrates each point with specific examples and presents a mechanistic approach to microbial reactions. Extensive cross referencing between chapters provides cohesion and complete coverage of issues tangential to each topic. The new edition has been extensively revised, and contains a new appendix, a new chapter, plus further revised information throughout the book. In fact, it is a completely new book.A major difficulty in environmental science is that much of the background is widely scattered in the specialized chemical, microbiological, and biological literature. The coverage of all these areas in a single volume, the coherence supplied by the cross references, and the extensive references to the original literature makes Organic Chemicals: An Environmental Perspective a unique resource.

Addressing the persistent environmental threat of organic chemicals with a fresh approach to degradation and transformation processes, Organic Chemicals in the Environment: Mechanisms of Degradation and Transformation, Second Edition examines a wide range of compounds as well as abiotic and microbiological reactions mediated by microorganisms. The book emphasizes the pathways used and the broad classes of enzymes involved. It provides an overview of experimental procedures with detailed coverage of the organic compounds that are considered to be xenobiotics. The book begins by providing a broad perspective on abiotic and biotic reactions, including the significance of a range of environmental determinants. The following chapters briefly introduce experimental procedures and emphasize those procedures for establishing the structure of metabolites using isotopes and physical methods. Next, the authors outline details of biochemical reactions involved in the biodegradation of the major groups of aliphatic, carbocyclic aromatic, and heterocyclic compounds. They end with coverage of bioremediation that has attracted increasing concern because of the hazard presented by the disposal of unwanted chemicals or by-products from their manufacture. Broad and comprehensive, this book provides a cohesive treatment of the subject. It contains an extensive set of literature references and numerous illustrative figures. The authors use a mechanistic approach with emphasis on the pathways, and the principles that emerge provide a guide not only for specific compounds but also for those having a more remote structural resemblance.

Organic Chemicals in the Aquatic Environment draws from the author's experience with a variety of problems dealing with the fate, distribution, and toxicity of organic compounds in the aquatic environment. It discusses the basic issues of chemical analysis, distribution, persistence, and ecotoxicology, with an emphasis on microbial reactions. The necessary input and the difficulties of achieving a rigorous synthesis of the various elements are illustrated with specific examples. The book includes a wide range of structurally diverse compounds as illustration and presents a mechanistic approach to biodegradation and biotransformation. The final chapter addresses the issue of environmental hazard assessment and constructs a strategy for carrying it out.

This volume addresses a broad spectrum of the environmental issues surrounding organic bromine and iodine compounds. It covers their partition among the environmental compartments and the potential for their long-range dissemination. The important issue of their atmospheric chemistry is discussed in detail in the context of ozone depletion and global warming, and the significant difference between the reactions of methyl bromide and methyl iodide are underscored. The mammalian toxicity is discussed and the mechanisms of the degradation and transformation of organic bromine and iodine compounds addressed. There has been considerable interest in naturally occurring metabolites in the current debate on the fate and partition of methyl bromide that is an important fungicide and is produced in substantial quantities as a metabolite of marine algae. The possible natural occurrence of diphenyl ethers that are used as flame retardants have also been raised. A discussion is given on plausible mechanisms for the biosynthesis of representative organic bromine and organic iodine metabolites. Reaction pathways are illustrated throughout and comprehensive references are given.

The volumes 3/I and 3/J present a modern account of polycyclic aromatic hydrocarbons (PAHs) and their heterocyclic analogs in the environment. The authors are internationally well recognized scientists belonging to those working presently in the frontline of the different subfields of this interdisciplinary area of environmental science; they give an integrated thorough overview on this hot topic. Extensive cross-referencing between chapters provides the readers with an easy access to all major areas. Due to the huge amount of material the text is published in two volumes (3/I and 3/J). It is expected that both volumes will soon become a major source of information and inspiration for all researchers actively working in PAH environmental chemistry or ecology.
